曲轴的主轴颈和曲轴颈的磨削质量很重要。意大利MARPOSS公司专门设计的过程中测量仪,可在切削过程中同时对一个或几个主轴颈进行检查,且对被检查的直径进行实时监控。首先将小型的测量头放在各个支承表面上,然后将尺寸控制数据反馈到机床的PLC控制器,待达到期望的尺寸时,控制器令各精密磨削装置逐个停止。这样可得到极窄小的公差带,并改善圆度,因此无需选配轴承,就可提高发动机寿命和各种性能。通常对主轴颈和曲轴颈进行磨削后,要求全部进行
The quality of grinding of the crankshaft crankshaft and crankshaft journal is important. Italy MARPOSS company designed in-process measuring instrument, cutting process can simultaneously check one or more of the main journal, and the diameter of the inspected real-time monitoring. First, the small measuring head on each bearing surface, and then the size control data back to the machine’s PLC controller, to achieve the desired size, the controller so that the precision grinding device one by one to stop. This results in a very narrow tolerance zone and improved roundness, which increases engine life and performance without the need for an optional bearing. After the main journal and crankshaft neck grinding, the requirements of all
